In addition, the Viper V10 was installed in the Dodge Ram SRT-10, earning the truck the Guinness World Record for fastest production truck (later bettered by the Australian Holden HSV Maloo, which uses the LS2, Corvette engine). The Dodge Tomahawk concept vehicle also uses this engine. Bitter Cars of Germany produced the Bitter GT1 based on the Lotus Elise GT1 using this engine.

The V10 was also sold to British luxury car manufacturer Bristol Cars: the Bristol Fighter was powered by a modified version of the engine which produced {{cvt|525|bhp|PS kW|0}}, increasing to {{cvt|550|bhp|PS kW|0}} at high speed due to the ram air effect.{{cite web|url=http://www.bristolcars.co.uk/BristolFighter.htm|title=Bristol Fighter|url-status=dead|archive-url=https://web.archive.org/web/20101028073207/http://www.bristolcars.co.uk/BristolFighter.htm|archive-date=2010-10-28}} Bristol Cars further produced a Fighter S, in which the engine was tuned to give {{cvt|628|bhp|PS kW|0}} ({{cvt|660|bhp|PS kW|0}} at high speed). Bristol had also planned to produce a Fighter T, further modifying the engine with a turbocharger to produce {{cvt|1012|bhp|PS kW|0}} at 5600 rpm.{{cite web |title=Bristol Fighter T Revealed |url=http://www.worldcarfans.com/10611075776/bristol-fighter-t-revealed |url-status=dead |archive-url=https://web.archive.org/web/20120703015624/http://www.worldcarfans.com/10611075776/bristol-fighter-t-revealed |archive-date=2012-07-03 |access-date=2010-07-08}} However, Bristol have since stated that no Fighter T models were produced{{citation needed|date=December 2023}}.
